APPARATUS FOR SCOURING, CLEANSING, AND POLISHING METAL, mirc.

SPECIFICATION forming part of Letters Patent No. 395,583, dated January l, 18189.

Application filed July 14, 1887 Serial No. 244,293. (No model.)

To all whom it may con/cern:

Be it known that I, JOHN PFEIFER, a citizen of the United States, residing' in the city and county of Philadelphia, State of Pennsylvania, have invented anew and useful Improvein ent in Apparatus for Scouriirsg1 or (f/leansin Metal, dse., which improvement is fully set :Forth in the following speci [ication and accomlianying drawings.

My invention consists of an apparatus for scouring or cleansingmetal, dre., embodying a brush with means for preventingl the material employed as the brush fiber `from being,l broken,and other features, as will be hereinafter set lforth and claimed.

Figure l represents a front viewof an appa ratus for scouringl or cleansing` metal, dsc., embodying, my invention. Fig. 2 represents a longitudinal vertical section thereof.

Similar let-ters ot' reference indicate corresponding' parts in the two figures.

Referring to the drawings, A represents a rising,` and falling table, which is guided on a stand, B, and having' connected with it a treadle, (l, whose'axis is on said stand.

Mounted above the table A is a rotary brush, D, which is termed of end pieces, E, having` a eoiiinecting,l drum or hub, E', to which latter is secured the brush material l?. The bars G are secured at their ends to the end pieces,E, and are placed back of the outer ends of the brush material F, the latter being,` formed oi strips of steel or other material suitable for scouringl purposes. The axle of the brush D has secured to it a pulley, ll, attached to ittor rotating the same.

The operation is as follows: Power is ap-y plied to the brush D, and the metal, dac., to be scoured placed upon the table A. The treadle is new operated, whereby the metal is raised and subjected to the action of the brush D,

the eli'ectof which is the seouringof the saine in a rapid and efficient manner. rlhe treadle is then. let go,whe1ieby the table descends and the metal, &c., maybe removed therefrom. The strain on the brush material severe, so that it is liable to bend and break; but this 'is prevented by the barsor rods G,which sustain the brush at its back, especially near the outer ends, without affect-ing the proper action of the same on the meta-l, dto.

In order to `guide the table true in its motions, it has secured to it the depeinlingl pin J, which passes freelythroug'h an opening, K, and boss K. The rod L, which is connected with the treadle and table A, is also passed freely through an opening, M, and boss M', said openings being in the top or table ot' the stand and said bosses depending' therefrom.

Having` thus described my invention, what I claim as new, and 'desire to secure by Letters Patent, is-

l. A stand, a rising and falling table mounted on said stand, and a treadle connected with said table, in combination with a brush secured to a rotary axle which is mounted on said stand above said table and provided with cross-bars back. ot' the brush material, form .ing together an iinprovementin apparatus for scouringl and cleaning metal, as stated.

2. An apparatus for cleansing metal, consistingl ot the rotary brush D, journaled in bearings on the stand B,the latter having the bosses lll and K', the table A on said stand and having the rod L and pin J, and the treadle C, securelfl to said rod L, said parts be ing' combined substantially as described.
